Android - two sentences, two styles, one TextView

Question

I am tyring to display a TextView that contains two sentences and I want them to be one after the other like this:

AAAAAA: BBBBBBBBBBBBBBBBBBBBBBB
BBBBBBBBB

where A... is the first word\part of sentence and B... is a second sentence.

the size of A... & B... isn't constant.

tried doing this:

    <RelativeLayout 
        style="@style/f13"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >
        <TextView 
            android:id="@+id/first_text"
            android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="AAAAAA: " />    
    <TextView 
            style="@style/f15"
            android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB"
        android:layout_toRightOf="@id/first_text" />                
    </RelativeLayout>

but i got:

AAAAAA: BBBBBBBBBBBBBBBBBBBBBBB
        BBBBBBBBB

and i want the second (B...) sentence to continue below the first sentence (A...) i should add that sentence A... & B... have different styles.

the style for A:

<style 
    name="f13">
    <item name="android:typeface">sans</item>
    <item name="android:textSize">15dp</item>
    <item name="android:textStyle">bold</item>
    <item name="android:textColor">@color/grey_dark_emperor</item>
</style>

the style for B:

<style 
    name="f15">
    <item name="android:typeface">sans</item>
    <item name="android:textSize">17dp</item>
    <item name="android:textStyle">normal</item>
    <item name="android:textColor">@color/grey_dark_emperor</item>
</style>

any thoughts ?

Answer 1

You can try to use the SpannableStringBuilder as follows:

String firstString = "AAAAAA: ";
String secondString = "BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB";

SpannableStringBuilder stringBuilder = new SpannableStringBuilder(firstString + secondString);
stringBuilder.setSpan(new StyleSpan(android.graphics.Typeface.BOLD), 0, firstString.length(),
            Spannable.SPAN_INCLUSIVE_INCLUSIVE);
stringBuilder.setSpan(new ForegroundColorSpan(Color.rgb(255, 0, 0)), firstString.length() + 1,
            firstString.length() + secondString.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE);
textView.setText(stringBuilder);

This will make the first sentence to be bold, and the second one coloured in red.
